Mid-Century Antibiotic May Offer Options After PARP Inhibitor Resistance

Novobiocin, an antibiotic discovered during the 1950s, may be a potential second-line therapy for patients whose tumors have become resistant to poly (ADP-ribose) polymerase (PARP) inhibitors, researchers reported in Nature Cancer. The finding may open up new options for patients with BRCA-variant disease such as breast, ovarian, pancreatic, and prostate cancer.
